Pros

Pro

Based around crowdsourced OpenStreetMap data

OSM provides a map editable by everyone; just like the web-based encyclopedia, Wikipedia.

Using a community edited map allows one to correct isses they encounter. Combined with the monthly turn around, these edits are added for navigation quickly.

Pro

Works offline once the maps are downloaded

Pro

Excellent general map viewing

Sometimes one needs more than just navigation, they have a need to view a map or specify a specific route. OsmAnd provides a very nice, detailed map. This can be good for seeing what is around you or showing a place you are talking about to a friend.

It also provides a means to add waypoints on the map which can be used to dictate a specific route (not simple enough to do routinely).

Pro

Routinely updated maps

Utilizing the community driven OpenStreetMap data has allowed for monthly publishing of new maps that the user can use. Though that doesn't necessarily mean the map data has changed.

Pro

OpenStreetMap contributing made convenient

One can also utilize features to contribute back to OSM. This includes reporting a bug or adding a POI. This feature doesn't require an internet connection as the points can be uploaded latter upon request.

Pro

Free and open source

Pro

Helpful lane guidance

Lane guidance can assist in deciding if one should stay in the right or left lanes. OsmAnd provides detailed information on the number of lanes and which are valid for your chosen destination; based on the data available it may show too many or too few lanes.

Pro

Contour lines enable understanding the terrain

Through the use of an additional plugin OsmAnd Maps & Navigation is able to utilize contour lines on its maps which helps view the landscape and terrain.

Pro

Shows speed limit

Pro

Notification about police

Pro

Live routing and alert reports from other waze users

Each waze user has the ability to report traffic and road information changes as well as accidents, road closures, police locations and other alerts in real-time. This information is then displayed on the map to benefit other drivers and used to recalculate optimal route.

Pro

Shows traffic speeds during rush hour

Shows red during heavy traffic along with mph, and orange for mild traffic.

Pro

Lists traffic accidents

Cons

Con

Poor navigation interface

The interface is not the most intuitive, though is continually progressing. It doesn't provide a 3D view like many navigation apps.

Con

Slow rendering

It can take some time for an area to be rendered. This tends not to be a problem during navigation since only a small area must be rendered as the map moves, and this area isn't immediately needed; though likely a bigger issue with smaller screens.

Con

No display when the next speed limit occurs

When driving on unknown streets you are often surprised by speed limits or town signs, so you have to friction brake.

Con

Slow and sometimes poor search

Most often does not find what you are looking for (which is not caused by bad OSM data).

Con

Terrible address data

This is a limitation of OSM's data, but it is unreliable for locating an address while offline. Even with internet it doesn't appear that it can locate most addresses.

Con

Being based on OpenStreetMap data can be lacking

The use of OSM also has the drawback of many places not getting the attention needed for updates. Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.

Con

Near impossible to scroll through map

Due to the slow rendering (already mentioned) it is near impossible to scroll through OsmAnd's maps. You move the map only slightly and it takes ages to redraw all vector layers.

Con

Advertisement supported

The advertisements usually shown when the vehicle is at rest, and they cover the entire screen. There is no way to get rid of them, it's strictly a free ad supported app.
